Just recently bought a NIB 431. Shoots very nice and recoil is surprisingly modest with the Federal HP 85 grainers that I was using. I like the 32 Magnum and have some ammo stashed just in case it becomes hard to find again. Starting to see it on the shelves more often lately. Can't speak for the 331 but the 431 is a nice pocket carry piece, light weight, 6 shots, pretty good ballistics that are in the area of some 380's, and more than a 22 mag. or 32acp.
